Nothing personal, but do Denis and Dolphin know each other already? You guys seem to be natural nemesis...
I think checking some video rentals in the library is the easiest. Don't know much about Ireland's library systems... or go to some video stores and rent cheap Britain history video... but you most likely find it in library, since video rentals tend to have Hollywood movies only.
Try to avoid Amazon, if you can. They are fairly expensive compared to other stores, and the shipping period of time and fee gets annoying sometimes.
I am sure that you can get library card, at the very least. I understand that you may be experiencing some financial difficulties... but I think you can manage few bucks.
